EW1346A Timloc Building Products – Thermo-loc Platinum Multi cavity closer


This is an assessment of Thermo-loc Platinum Multi, an insulated cavity closer suitable for second fix applications, around window and door openings in masonry, timber or steel frame cavity construction. The function of the product is to provide an insulated DPC at jambs and sills at window and door openings,
thereby reducing condensation, and alleviating cold bridging and mould growth in those areas. The rigid uPVC profile, housing 20mm thick expanded polystyrene insulation is supplied in two standard profiles to accommodate cavity widths 50-100mm (Thermo-loc Platinum Multi 100) and 100-150mm (Thermo-loc Platinum Multi 150).
